In the Great Seljuk Period (1040-1157), an observatory was established in the capital Isfahan during the reign of Sultan Malikşah (1072-1092). A delegation of eight people, chaired by Umer Khayyâm, worked in this observatory. One of the important names within this delegation of scientists working at the Isfahan (Malikşah) Observatory is Abû’l Abbâs al-Lawkarî. There is no information on how al-Lawkarî’s works at the Isfahan (Malikşah) Observatory and at what level it contributes to the study of observations. But, there should be no doubt that he was invited to the Isfahan (Malikşah) Observatory for his knowledge and academic identity. Al-Lawkarî, who has made a name for philosophy rather than astronomy, is a student of Bahramyar b. Marzubân who is a student of Avicenna. Many of Avicenna’s teachings on philosophy were transferred to al-Lawkarî through Bahramyar b. Marzubân. Al-Lawkarî played an important role in spreading the philosophical teachings of Avicenna to Khorasan. Al-Lawkarî, who wrote many works during his life, came to the forefront with his philosophical work entitled “Bayân al-Haqq bi-Damân al Sıdk”. He also trained many students and his peers in the field of philosophy leave behind Umer Khayyâm, İbn Kûşek and al-Vâsıtî.
